I liked this a lot and so did the husband. It is supposed to be a side dish, but I ate it as an entree with a side of spinach. The husband ate a smaller portion as a side (along with some spinach) to his meatloaf. I used less cheese (only 3/4 cup) since he isn't a fan of it and he said it was fine. I also tasted the sauce before baking and it really needed something else (it was pretty bland) so I added some nutmeg. That made it delicious! Also, the recipe says to use a 2 qt. casserole dish. I used a 2.5 liter dish, which is about 2.6 quarts and it was almost full. Go with a bigger dish.
